Email plug-in works with SSL and no security but fails with TLS on port 587 at TMD Hosting - see below.

Looks like a problem with your SSL lib version on your hosting provider.

Thank you, Andy. Message from TMD below, FYI. I am passing your note back to them. SSL works so we are using that. However, upon testing this with the TLS method, it seems it responds with the same error message you have provided, which seems to be caused by your Grav-based website and how the PHP Hooks that establish a TLS Connection work. Unfortunately, we will not be able to assist you with resolving the issue with the TLS Encryption, and you should contact an experienced web developer for further assistance on the matter, but if you wish to have your messages sent via an encrypted connection, you can always use the SSL Method (465 Port).

Well, we're just using Swift email library, and the error comes from there. Swift is the most widely used, and most robust email library available, so if it doesn't work with TMD, i'm going to bet the problem lies on their end, and not on Swift. :)

Glad you are able to use SSL though.

To avoid prolonging this agony I have just sent this suggestion to TMD: As we have a solution (SSL instead of TLS) I suggest avoiding detailed technical investigation by waiting until your version moves up from OpenSSL 1.0.2k (26 January 2017) to 1.0.2p (14 August 2018). Ian
